NDJSONtoCSV

Convert NDJSON to CSV

Up to 3 files at once, 100 with Pro. Mixed formats are fine.

One JSON object per line. What log pipelines and data exports stream. A table as plain text. Every spreadsheet, database and analytics tool reads it.

How to convert

  1. Drop your NDJSON file onto this page, or click to pick one.
  2. Choose CSV as the target. The conversion runs inside your browser — the file is never uploaded.
  3. Download the finished CSV file.

What to expect

Quality
The result is a close reconstruction rather than an exact copy. Check it before relying on it.
Where it runs
This conversion runs inside your browser. Your file is never uploaded, and it works with the network disconnected.
What can be lost
Nested objects are flattened into columns. Deeply nested data loses its shape.
